The New Patek Philippe Twenty~4 7340/1R Perpetual Calendar

Introduced in 1999, the Twenty~4 collection was Patek Philippe’s first dedicated line of feminine timepieces. The original model featured an Art Deco-inspired manchette (cuff) design, but in 2018, the brand unveiled the Twenty~4 Automatic, which is a round-cased iteration powered by an automatic movement. This year, Patek Philippe elevates the collection further by introducing a perpetual calendar complication, marking the collection's debut in the realm of Grand Complications.
Crafted entirely in 18K rose gold, the watch features a 36mm case with a slender profile of just 9.95mm, making it sit gracefully on the wrist. The case is meticulously finished with a combination of polished and brushed surfaces, enhancing its refined aesthetic. Two dial options are available. The Ref. 7340/1R-001 features a silvery opaline dial with a vertical satin finish, evoking the texture of shantung silk that feature irregular texture, while the Ref. 7340/1R-010 presents an olive green sunburst dial for a more contemporary appeal.

Ratchet wheel

Ratchet wheel

Is a gear-like component that is located on top of the barrel. It is attached to the arbor of the barrel using a screw. When the watch is being wound, the ratchet wheel turns and helps in coiling the mainspring tightly, storing potential energy. This energy is later released to power the watch's movement. The ratchet wheel is designed to rotate in one direction only, preventing the mainspring from unwinding in the opposite direction. It is an essential part of the winding mechanism that ensures the efficient and controlled winding of the watch.
